I think laughter is one of my favourite things in the world. It feels so healthy.

Apparently there is such a thing as 'laughter therapy'. According to teehee.com (seriously) there are three reasons to laugh...

1. It strengthens your immune system.
2. It makes your cheeks sore.
3. It increases your intellectual performance and boosts information retention.

I think that number two is a little dubious, but I was already convinced anyway.

Bring on the sore cheeks, I say!
